Just off the Las Vegas Strip, there's a big white building in a run-of-the-mill office complex where tourists can pay as little as $50 to shoot 25 rounds from an AK-47. A billboard out front with a busty woman wielding a machine gun advertises the "ultimate shooting experience."

From the parking lot, you can see the Mandalay Bay. That's the hotel where 58 people were killed and nearly 500 were wounded on Sunday night during a country music festival.

Americans are drinking a lot less milk than they used to. According to the U. S. Department of Agriculture, the average person drinks 18 gallons a year. Back in the 1970s it was more like 30 gallons a year. We once hoisted a glass with dinner, soaked our breakfast cereal or dipped into the occasional milkshake. This habitual milk drinking was no accident.
